Summary
Hammer toe in patients with hallux valgus (HV) significantly worsens dynamic postural stability and increases fall risk. This finding highlights the importance of addressing both conditions for better balance in HV patients.
Area of Science:
- Orthopedics
- Biomechanics
- Gerontology
Background:
- Hallux valgus (HV) is known to compromise postural stability.
- The impact of co-occurring hammer toe on postural stability in HV patients is not well-established.
Purpose of the Study:
- To investigate the effect of comorbid hammer toe on static and dynamic postural stability in patients with hallux valgus.
Main Methods:
- Assessed 45 patients with HV, stratified into groups with (H(+)) and without (H(-)) hammer toe.
- Utilized stabilometer for static stability, and Berg Balance Scale (BBS), Timed Up and Go (TUG) test, and Falls Efficacy Scale-International (FES-I) for dynamic stability.
Main Results:
- No significant differences in static postural stability between groups.
- Group H(+) exhibited significantly lower BBS scores and higher TUG and FES-I scores compared to group H(-).
Conclusions:
- Comorbid hammer toe negatively impacts dynamic postural stability in patients with moderate-to-severe bilateral HV.
- The presence of hammer toe increases the risk of falls in this patient population.
